Hey all. New mini owner here. First timer .
We have a 54 plate cooper S car.Not had it long, a few months. It has an almighty wind or whistle noise coming in somewhere in the front passenger side area under the dash or somewhere. It starts around 50 mph and is quite a nuisence. Is there a likely culprit. Ive had a look in and around but its pretty built up under there. Ive reseated the door seals and open and closed the vents but it's not that.
It could be coming from anywhere in there I guess.
Any thoughts anyone?

Well, I have just fully taped over the cooper S emblem & repeater
on the side wing & vent. Ill give it a try later and see if that was it. As for the window, They all look like original marking windows but who knows....

Just tested the car on the motorway and it has gone!!!!!!!!!! Guys ..Nice one.Thanks alot Nun man!!
The repeater is taped over and no loud dreadfull whistle. Anyone know what the other person who had this did to stop it then..
Currently looks like a mini with a band aid on .. Although kinda does look bespoke!!!

Love forums I do.

Just check the vent fixings are intact and not broken so the assembly fits flush and tight to the body.
